Melissa's parents divorced before the killings began, but she says she got a sick feeling whenever her father came to visit.

"His appearances to visit us were so random. He would never call or tell us. But I'd have this instinct that my father was coming. It was like a form of anxiety," she says. "It would start building and building, and I would tell my mom: 'I know Dad's coming. He's going to visit us.' But when I was around him, I felt this intense stomach-turning feeling."
